Tesla's death-mask

This death mask of Nikola Tesla is on display at a museum in Belgrade, Serbia. Does anyone know if you can have a death mask cast if you're also an organ donor? Does cornea, etc, harvesting interfere with the mask-making? Because I'm an organ donor, but man, I'd love to leave behind one of these babies.
